Is it bad or okay?

I'm posting twice today! So yeah my 2 years old has a stomach bug and everytime he throws up he gets so sad and it's everywhere on him and it smells bad, so I've given him a bath. He adores baths, it's the best thing he knows so it has really cheered him up, and it also makes him clean. He's taken two baths today so far. Is this a bad strategy? Can you bath too much? It's obviously only as long as he's sick. I put baby oil in the bath to prevent his skin from becoming dry. Is there anything else I can do?
